Poot service

My PVR setting have not been working for 2 weeks and when I call the contact centre, they tell me there is nothing wrong on thier side. I have been calling and sending emails but nothing. I pay my subscription every month and I expact multichoice to treat me fair. I spoke to 1 of thier agents last week and the lady was yowning on the phone. She kept on doing this as a result she did not help me. Multichoice is messing up and they need another company that will compete with them daily.
